Autonomic modulation of assessment in individuals with Down syndrome in hippotherapy

Abstract

Introduction: The hippotherapy is a therapeutic modality that serves largely individuals with Down syndrome, because they have motor, cognitive and socio-emotional changes. It is known that changes in heart rate are modulated by the autonomic nervous system, however, in the literature there are no descriptions of the variability of heart rate in these practitioners, especially in the activity related to hippotherapy. Objectives: To evaluate Heart Rate Variability in practitioners of hippotherapy with Down Syndrome. Methods: Six children with Down Syndrome were recruited, age rate of 12 ± 1.6 years. The Heart Rate were evaluate using a cardiofrequencimetre – Polar (RS800CX), before, during and after 5 sessions of hippotherapy once weekly. Results: There were tendency of decrease in the parasympathetic activity during initial rest between first and fifth sessions, and significant decrease of the parasympathetic activity observed by the value of pNN50 compared to the Heart Rate during the first and fifth sessions. Conclusions: This study has shown that children treated with hippotherapy had tendency to have their Heart Rate Variability decreased.
